feat: add support for custom openai compatible provider (fixes #2102)

[ashishSoni1234]

Summary

• Added support for a custom OpenAI-compatible provider. Users can now input a Base URL, Model Name, and API Key to connect any OpenAI-compatible API endpoint via the AI Providers settings UI.

Why

• To address the need for using custom endpoints and API keys, specifically allowing users to connect to Nous Research's OpenAI-compatible inference API or other smaller providers.

Issue

• Closes Support Nous provider / custom OpenAI-compatible endpoint #2102

Scope

• Modified store.ts to handle custom provider storage in opencode.jsonc.
• Updated provider-auth-modal.tsx to display the "Custom OpenAI Compatible" option.
• Hooked up routing changes in session-route.tsx and settings-route.tsx.
